Try This At Home: Liquid Layers
In our last Try This At Home video we looked at the buoyancy of aluminum in different shapes and talked about how it compares to density. In this video, we will be experimenting with liquids to see if we can make layers. If you try this at home you can try other liquids too including different types of oil, corn syrup or maple syrup, and rubbing alcohol. You can even make solutions with water and different amounts of salt (adding salt will increase the density).
Try This At Home: Buoyancy
In light of the state of the world right now where everyone is feeling like they need to stay at home, we put together a video with an experiment that you can do with things you probably already have in your house. Check out our new YouTube Channel and subscribe. We will be adding more content regularly.
